Thanks to our BBCode parser your users can now make use of the entire Emoji keyboard when posting on your board. From a lovely grin to a pink unicorn, Emoji can liven up all posts on your board! With phpBB 3.3, support for Emojis has been extended further to also support them in other parts like topic titles.
PHP 7 works twice as fast as previous PHP versions. We have modified phpBB to now completely support the latest releases of PHP (7.1 to 7.4) so you can enjoy all these performance advantages.
